Crooker Antiparallel merging model results in a wedge-shaped Cusp that rotates with IMF By
• Figure depicts northern polar cap (shaded) for pure (a) By and (b) - By
• Edges map to neutral lines in opposite hemispheres
• Most energetic particles towards the edges, least energetic in the center
• Green satellite tracks will see a “double” or “V” cusp
• Red satellite tracks will see normal cusp dispersion pattern
